aryepiglottic folds
A ring of connective tissue and muscle extending from the tips of the arytenoid cartilages to the larynx. They separate the laryngeal vestibule from the pharynx and help preserve the airway.
ventricular folds
AKA false VFs
Vibrate only at very low fundamental frequencies and usually not during typical phonation (i.e. coughing, lifting heavy items)
pharyngeal plexus
Formed by the joining of cranial nerves X (vagus) and XI (spinal accessory) to innervate upper pharyngeal muscles.

malocclusion
deviation from the normal positioning of the upper teeth against the lower teeth
